Hi
1). Make sure that Hyperterminal is communicating properly with Internal Oscillator before programming in flash magic GUI.
2). If autobaud error occurs while downloading the hex code, try to communicate with terminal in flash magic (Tools->Terminal) if this communication established fine as same Hyperterminal then close (while closing if flash magic doesn't respond properly then kill that process in windows task manager) and reopen flash magic, now hex code can be downloaded easily with Flash magic GUI without external crystal.

Sandeep.
